如何在 Latex 中绘制下表?
我努力了:
\begin{table}[h!]
\centering
\begin{tabular}{|c|c c |c c|}
\hline
& c &c & a & a \\ [0.5ex]
\hline
Performance measure & $\hat{\mu}$ & $\hat{\si}$ & $\hat{\mu}$ & $\hat{\si}$ \\
\hline\hline
MSE & 0.0589 & 0.0302 & 0.0611 &0.0456 \\
Bias & 0.0243 & -0.0415 &0.0332 & -0.0496 \\
SD & 0.242 & 0.169 & 0.245 & 0.208 \\[1ex]
\hline
\end{tabular}
\caption{Sample size is $n=20$.}
\label{table:1}
\end{table}

\documentclass {article}
\usepackage{multirow}
\usepackage{booktabs}
\usepackage{tabulary}
\usepackage{siunitx}
\begin{document}
\centering
\section*{Poor man's version:}
\begin{tabular}{|c|c c |c c|}\hline
\multirow{2}{*}{\parbox{6em}{\centering Performance measure}} & \multicolumn{2}{c|}{c} & \multicolumn{2}{c|}{a} \\\cline{2-5}
& $\hat{\mu}$ & $\hat{\sigma}$ & $\hat{\mu}$ & $\hat{\sigma}$ \\\hline
MSE & 0.0589 & 0.0302 & 0.0611 &0.0456 \\
Bias & 0.0243 & -0.0415 &0.0332 & -0.0496 \\
SD & 0.242 & 0.169 & 0.245 & 0.208 \\\hline
\end{tabular}
\section*{Glamorous version:}
\begin{tabulary}{\linewidth}{LS[table-format=1.4]SSS}\toprule
\multirow{2}{*}{\parbox{5em}{ Performance measure}}
& \multicolumn{2}{c}{c} & \multicolumn{2}{c}{a} \\
\cmidrule(rl){2-3} \cmidrule(rl){4-5}
& {$\hat{\mu}$} & $\hat{\sigma}$ & $\hat{\mu}$ & $\hat{\sigma}$ \\\midrule
MSE & 0.0589 & 0.0302 & 0.0611 &0.0456 \\

你想要这样的东西吗?
\documentclass[12pt]{article}
\usepackage[a4paper, total={180mm,257mm},left=15mm,top=20mm]{geometry}
\usepackage{stix}%<-- for using the Ldsh arrow
\usepackage{tabularray}
\begin{document}
\begin{tblr}{colspec={Q[3cm,l]Q[1.5cm,l]Q[1.5cm,l]Q[1.5cm,l]Q[1.5cm,l]},cell{1}{2,4}={r=1,c=2}{l},rows={1cm,m},hlines,vlines,hline{2}={leftpos=-1, rightpos=-1},hline{2}={1}{leftpos=0, rightpos=0},cell{1}{1}={r=2,c=1}{l,h},vline{3,5}={2-5}{abovepos=-3, belowpos=-3}}
\raisebox{-7pt}{C} & C & C & C & C \\
C & a & b & a & $b^{\Ldsh}$ \\
A & &$\Ldsh$ & &$\Ldsh$ \\
